A force of 6500 dyne is applied to a body with a mass of 130g. What is the acceleration?
1. A force of 6500 dyne is applied to a body with a mass of 130g. What is the acceleration?
Answer:
a = 0.5 [tex]\frac{m}{s^{2} }[/tex]
Explanation:
Given:
F = 6500 dyne
m = 130g
Required:
Acceleration ( a) = ?
Solution:
The formula for force is
F = mass x acceleration
F = m x a
F = 6500 dyne by converting it to Newton (N) we will get
F = 6500 dyne x [tex]\frac{0.001N}{100dyne}[/tex]
F = 0. 065N
Convert g to kg
m = 130g x [tex]\frac{1kg}{1000g}[/tex]
m = 0.13kg
0.065N = 0.13kg x a
a = [tex]\frac{0.065N}{0.13g}[/tex]
a = 0.5 [tex]\frac{m}{s^{2} }[/tex]

16. WHAT IS THE PERCENT BY MASS OF A SOLUTION MADE BY DISSOLVING 40.0g OF SUGAR INTO 130g of WATER? A. 10% B. 20% C. 23.5% D. 80%
C. 23.5%
• What is the percent by mass of a solution made by dissolving 40.0 grams of sugar into 130 grams of water?
Equation:% by mass = (mass of solute/mass of sol.)•100%
Note:
mass of sol. = mass of solute + mass of solvent
Solution:% by mass = (40.0g/40.0g+130g)•100%
% by mass = (40.0g/170.0g)•100%
% by mass = 0.23529 x 100%
% by mass = 23.5%
17. which among the reactant is consider as limiting reactant? Each reactant has 130g Au+3HNO3+4HCI > HAuCl4+3NO2+3H2O
To determine the limiting reactant in a chemical reaction, we need to compare the amounts of each reactant present and calculate how much product can be produced from each reactant. The reactant that produces the least amount of product is the limiting reactant.
Using the balanced chemical equation:
Au + 3HNO3 + 4HCl → HAuCl4 + 3NO2 + 3H2O
We need to determine the amount of product (HAuCl4) that can be produced from each reactant. To do this, we need to convert the amount of each reactant given into moles, and then use stoichiometry to calculate the amount of product.
Assuming that the units for each reactant are grams:
130 g Au x (1 mol Au / 196.967 g Au) x (1 mol HAuCl4 / 1 mol Au) = 0.6597 mol HAuCl4
130 g HNO3 x (1 mol HNO3 / 63.01 g HNO3) x (1 mol HAuCl4 / 3 mol HNO3) = 0.6936 mol HAuCl4
130 g HCl x (1 mol HCl / 36.46 g HCl) x (1 mol HAuCl4 / 4 mol HCl) = 0.9451 mol HAuCl4
Based on these calculations, the limiting reactant is Au, because it produces the least amount of product (0.6597 mol HAuCl4) compared to the other reactants (0.6936 mol HAuCl4 for HNO3 and 0.9451 mol HAuCl4 for HCl). Therefore, Au is the limiting reactant in this reaction.
18. Mary and Zoe wanted to find the volume of a 130g empty box of soap.First, they filled the box with marbles. About 30 marbles were put in the box.Then, they put peanut seeds inside the box. About 238 peanut seeds filled the box.Finally, They filled the box with corn kernels. About 346 grains heaped the box. Compare The volume of the 130g empty box of soap.a.What have you noticed?b.Why did that happen?c.Do the non- standard units of measurement give consistent and accurate volume?Why?
Answer:
1.The values are different
2.These are non-standard units of measurement
3.There is no consistentcy and accuracy in non-standard measurement units, because they are different standards.

19. In the chemical Formula AgCl, it is analyzed to contain 73.52%. silver. if there are 130g sample to be used in making photographic paper, how many grams are silver?
Answer:
If the chemical formula AgCl contains 73.52% silver, and there is a 130 gram sample of it, then there would be 130 grams x 73.52% = 96.2624 grams of silver in the sample.
